Retrograde Rock "Niku" Defies Orbital Trend
The discovery of trans-Neptunian object 2011 KT19 in a strange orbit deepens a key mystery in the outer solar system.
Dawn at Ceres: The Inside Story
Careful tracking of NASA's Dawn spacecraft reveals that Ceres has a rocky core and a thick ice-and-salt crust. Maybe a briny ocean still lies buried inside.
Possible Replacement for Hitomi
JAXA and NASA are looking at the possibility of replacing the dead Hitomi X-ray observatory, with a potential launch around 2020.
Mars 2020 Rover Construction Moves Ahead
The Mars 2020 rover reached a third crucial milestone this past week on the path to the launch pad.
NASA's Juno Probe Reaches Jupiter
After a 5-year-long journey, NASA's latest emissary to the largest planet in the solar system has arrived at its destination.
LISA Pathfinder Surpasses Expectations
First science results from ESA's LISA Pathfinder mission exceed expectations, with five times the sensitivity. This result paves the way for a future full-scale gravitational wave observatory in space.
Amateur Astro-imagers Get Ready for Juno
Planetary scientists are counting on amateur observations to enhance the results from NASA's forthcoming Juno mission.
Watch the International Space Station Marathon
The orbiting science laboratory begins a series of marathon passes this week that favor the northern hemisphere.
ExoMars Rover Launch Delayed Until 2020
The European Space Agency is opting to send its first rover to the Red Planet two years later than originally planned.
Russian Space Observatory Launches
Russia's Mikhailo Lomonosov observatory takes to the skies on the hunt for gamma-ray bursts, cosmic rays, and near-Earth asteroids.
Recovery Attempts End for Hitomi X-ray Satellite
The Japanese space agency JAXA has released a timeline covering the Hitomi space observatory's failure last month. Salvage efforts continue but recovery appears unlikely.
NASA's Kepler Spacecraft Recovered from Emergency Mode
The Kepler team unexpectedly found the planet-hunting spacecraft in emergency mode on April 7th, but with the spacecraft recovered, hopes are high that its newest search, this time for rogue planets, is still on. Read on to see how amateur observations can help!
$100 Million for Fast Probes to Alpha Centauri. Yes, Really.
Yuri Milner commits $100 million to Breakthrough Starshot, a research and development project toward sending interstellar nanoprobes to Alpha Centauri.
Malfunction Cripples Hitomi X-ray Observatory
Ground controllers are scrambling to recover the Hitomi satellite from a mysterious 'debris anomaly' over the past weekend.
Pluto's Atmosphere Confounds Researchers
Observations by NASA's New Horizons spacecraft, combined with new modeling of long-term trends, suggest that Pluto's atmosphere is far more dynamic than anyone imagined.
Mars Gravity Map
By tracking deviations in spacecraft orbits, planetary scientists have created a high-resolution map of the Red Planet's gravitational pull.
ExoMars Trace Gas Orbiter Heads to Space
The launch of ESA's ExoMars Trace Gas Orbiter and Schiaparelli lander heralds a new phase of Mars exploration.
CANYVAL-X: Two CubeSats, One Telescope
An innovative CubeSat mission, slated to take to space this year, will demonstrate the feasibility of free-flying satellites.
The Mystery of Pluto's Floating Hills
Among its other geologic oddities, Pluto has clusters of hills floating in a frozen "sea" dominated by nitrogen ice. These bobbing bumps might hold clues to the plain's depth and evolution.
Smack! Booster Impact Site Found on Moon
The Lunar Reconnaissance Orbiter has finally spotted the impact of the Apollo 16 booster, more than 43 years after it happened.
